IMPROVEMENT IN MOTIVE POWERS..

Specification forming part of Letters Patent No. 122,802, dated January16, 1872.

Be t known to whom it may concern That I, AnoLPH BOUGEARD, of the cityof New Orleans and State of Louisiana, have invented certainImprovements in Motive Power;

` and I hereby declare the following to be a full,

clear, and exact description ofthe same, reference being had to theannexed drawing, which forms a part of this specification.

My improvement relates to a simple mechanical power which is designed tobe especially applicable to the operation of sewing-machines, or oth ermachines requiring but limited power, my object being to provide a motorwhich shall operate entirely independent of the person working at themachine, to the end that his whole attention may be entirely devoted tothe work in hand. In the operation of the sewing-machine to produce workof very great delicacy and neness, it is well known that when the footis applied to the treadle to work the machine the physical ei'ortexpended thereby diverts the attention and exhausts the power of theoperator. Therefore it frequently becomes absolutely essential that themachine should beoperated entirely independently of such person. 'Topersons, especially females, of feeble health and delicate physicalpowers the operation of the sewing-machine, although perhaps necessaryto their existence, becomes a serious, burdensome task, and in manyinstances of long and continued application it is known to havepermanently crippled them. The application of my device obviates theobjectionable difficulties above men tioned; diversiiies the operationby requiring the hand to be brought into exercise in wind ing up themachine; and when the operator sits down to the work his whole attentioncan be freely devoted thereto 5 and thus the whole operation becomeseasy and pleasant, all of which advantages I have fully demonstrated byactual experiment.

My device will be better understood and appreciated by reference to thedrawing, whereon it is clearly shown and amply illustrated, and whereon,at-

Figure 1 is shown a side elevation with portions thereof broken away themore clearly to expose to viewr certain important parts hereinafterspecified; While Fig. 2 is an end elevation, whereon is exhibited theparts of my device not plainly shown in Fig. l.

By reference to the drawing it will readily be perceived that the movingpower of my device consists of a suspended heavy weight, A, confinedwithin an upright rectangular cylinder, B, in which it loosely slides asit is elevated by means of hand power applied to the crank c, or as itdescends by its own gravity while operating any machine to which it maybe applied in practice. The heavy weight A aforesaid is suspended fromthe pulley-blocks b and c, which are secured to the top of the saidupright cylinder B, and through which the rope d is made to pass, to theend of transmitting thereby the power developed by the descending weightto the drum C. As the weight descends it is clearly obvious that thesaid drum C is made to revolve and with it the main cog-wheel c, whichturns loosely upon the shaft o as the weight is elevated, but when theweight descends it is rigidly connected to drum C by means of theratchet-wheel n, pawl l, and spring t. Through the pinion f, spurl Wheelg, and pinion h the power is furthermore transmitted to the driving-beltwheel t', from which, by means of a cord or belt, motion may be impartedto a sewing-machine or any other machine or device requiring amechanical motor of the character to whichthis relates. My device isfurthermore provided with a flywheel, p, for the purposes of securinguniformity and regularity of movement in practice. E is a frame, of woodor metal, which furnishes the bearings for the shafts o c s and thegearing therewith or thereon placed.

My device is simple, economical, and effective, and having described it,

What I desire to secure by Letters Patent is the following claim: Y

The arrangement of the wheels e, f, g, h, t', and p upon the shafts o,c, and s, with drinn C, ratchet u, pawl Z, spring t, in combination withthe weight A, cylinder B, blocks b and c, and rope d, substantially asdescribed, for the purposes set forth. l
